by Dr. Mackay (Flor. Hib., p. 135), is closely allied to the 

 " palmate " Ivy often cultivated in gardens. It is remarkable 

 from the resemblance which its leaves bear to those of a 

 Passion-flower ; they are deeply cut, 3-7 lobed, and usually 

 cuneate from the base. This Ivy is said to have been found 

 growing wild near the former Nursery Gardens at Dungans- 

 town, Wicklowj and is, we believe, the same plant which 

 is often inserted in nurserymen's catalogues as H, I^lix, 

 var. incisa. The scales on the panicles are 12 to 14 or 

 15-rayed, and Dr. Seem.ann has referred it as a variety to 

 H. canariensis (Journal of Botany, Vol. iii., p. 201), b^t we 

 believe that it should rather be placed under H. JJelix. 

 Whether the plant reported as found in Kerry, and in the 

 South Isles of Arran, in Galway Bay, be the triie R. 

 canariensis, is a question that must be left for further inves- 

 tigation. Some leaves recently received from the Azores 

 seem to agree partly with the so-called " Irish Ivy," others 

 come near to H. Regneriana.
